GARMENT- FASTENER.

Specification of Letters Patent.

Patented Sept. 11, 1906.

To all whom it may concern:

Be it known that I, J AOOB M. STEINHARDT, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Garment-Fasteners and I do hereby declare the following to be a full, clear, and exact description of the inven tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to numerals of reference marked thereon, which form a part of this specification.

This invention relates to that class of gar- 111ent-fastenersin which ball and socket members are used to join the parts of the garment.

The objects of the invention are to obtain greater durability in the construction of the device, to obtain greater security in a garment the parts of which are connected or fastened by such members, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts.

The invention consists in the improved garment-fastener and in the arrangements and combinations of arts of the same, all substantially as will e hereinafter set forth and finally embraced in the clauses of the claim.

Referring to the accompanying drawings, in which like numerals of reference indicate corresponding parts in each of the several figures, Figure 1 is a plan of one member of my improved fastener. Fig. 2 is a plan of the cooperating member. Fig. 3 is a sectional view of the two members taken through the axes of the said members and showing said members in their cooperating relation, and also showing in dotted outline the members detached from one another.

In said drawings, 5 indicates the male, inner or ball member of the improved fastener, and 6 cooperating female or socket member. The said outer member 6 comprises a plate of sheet metal formed or pressed up at its center into the desired shape by suitable formers, dies, or tools, and comprising an annular hollow rib 7, which is of double thickness, the inner part 8 of which provides an inclined interior wall, which forms a chamber that is larger at the base of said rib. At the center of said chamber the sheet metal plate is again raised, as at 9, to form a stud or post,

' which is also hollow and approximates a cone in sha e. It extends upward within the said cham er formed by the annular rib or part 7 to a point below the horizontal plane of the upper edge of said annular part, as shown in Fig. 3.

The inner male or ball-like member 5 comprises also a flat sheet-metal plate, which is raised or protrudes at its center to form the projection or protrusion 10, approximating the shape of a ball and being transversely split, as at 101, as by a saw, as shown in Fig.-

1. The center of the protrusion 10 in the line of the cut or split 101 is returned to form a stud-socket 12, the interior walls of which are inclined in correspondence with the inclined sides of the conical post 9. The outer face of the protrusion 10 is also backwardly inclined, as at 14, or inclined toward the socket 12, so as to guide the end of the post 9 into its socket. The inclined wall 11 of the socket 12 fits closely against the post 9 When the parts are in cooperative relation. The raised portion 10, at its outer edges 13, engages the inclined walls of the annular part 8, and thus there is a double bearing provided for the inner member against the outer member, one of said bearings being at the center wall 12 of the part 10, the other at the outer periphery of the said part 10. By this construction the members will not readily separate when the parts of'the garment'to which the said members are attached are under tension, and yet the said members can be readily parted when pressure is brought in the direction of the axes of said members. The saw cut or slit of the raised part of the member 10 piece of metal bent to form a double-walled socket and a central post, the secondmember consisting of a single piece of metal bent to form a protrusion, to enter the double-walled socket of the first member, and then bent to form a tapered socket for the post on the first member.

2. A garment-fastener comprising a pair of members, one member consisting of a single sheet of metal having a flange and bent out Ward and then back to form a double-Walled socket and then formed into a central post, the second member consisting of a single sheet of metal bent to form a flange, then bulged to form a radially split protrusion to fit the socket of the first member, and then bent in to form an open-ended socket for the post of the first member.

3. A garment-fastener comprising a pair of members, one member consisting of a single sheet of metal bent to form a double-Walled socket, the socket having a central post, the second member being bent to form a protrusion to approximately fit the socket of the first member and having a slitted socket to slide over the central post of the first member to force the protrusion and the Walls of the socket into close contact.

In testimony that I claim the foregoing I have hereunto set my hand this 9th day of December, 1905.

JACOB M. STEINHARDT.
